I11 the form shown the pivotal connectionbetween the oscillatory and rotary shafts is effected by mounting asleeve or hearing member 8 on the angular portion 5 on the rotary shaft.Said bearing member 8 is provided with two oppositely projecting arms ortrunnions 9 which project through hubs 10 formed on arms 11 of ayoke-shaped member secured to or forming part of the oscillatory shaft7.

The oscillatory shaft 7 is mounted in suitable bearings 13 which aremade adjustable so that the angular relation between said shaft and therotary shaft may be changed. When the oscillatory shaft is arranged atright angles to the rotar shaft as shown in full lines in Figs. 2 an 3,the rotation of the rotary shaft will caus.-: the oscillatory shaft tooscillate about its longitudinal ZIXIS' with a similar motion in bothdirections, and the forward turning movement of the oscillatory shaftwill take place in the same time as its backward turning movement. Whenbearing 13 is moved so as to throw the shaft 7 into the position shownin dotted lines in Fig. 3, the character of the oscillations of theoscillatory shaft will be changed, the turning movement thereof in onedirection being comparatively slow while its return movement, is morerapid, or in other words the turning movement of the oscillatory shaftin one direction occupies a greater length of time for its completionthan does the return movement. In any position of the oscillatory shaftthe trunnions 9 move back and forth in a plane which is situated atright angles to the axis of said shaft.

In substituting my improved mechanical movement for a cam, the part tobe oscillated or reciprocated may be connected to any moving part of thedevice but preferably either to the shaft 7 by a crank or otherequivalent connection, not shown, or

to one of the trunnions 9 and by varying the angular position of theoscillatory shaft relative to the rotary shaft the character of themovement imparted to the reciprocating or oscillating element may bechanged as desired so that said element may be iven the same characterof movement in bot directions, or may be given a quick movement in onedirection and a slow return movement, or the length of time which theelement rests at the end of each stroke may be varied merely by'varyingthe angular positipn of the oscillatory shaft relative to the rotaryshaf It will be noted that this construction is a balfl'fiCUd"0ne inevery particular and capable of substitution for almost any known cam.

Having described my invention, what I claim as new and desire to secureby Letters Patent of the United States is 1. In a mechanical movement, arotary shaft having a portion standing at an angle to the axis ofrotation of said shaft, an oscillatory shaft adapted to rotate about itslongitudinal axis, said shaft having an angular relation to the rotaryshaft, and a swivel connection between said oscillatory shaft and theangular portion of the rotary shaft, said oscillatory shaft beingadjustably mounted to vary the angular relation between it and therotary shaft.

2. In a mechanical movement, a rotary shaft having a portion standing atan angle to its axis of rotation, a sleeve or hearing member looselymounted on the angular portion of the shaft, and an oscillatory shaftadapted to turn about its longitudinal axis and pivotally connected tosaid sleeve or hearing member, said oscillatory shaft being adjustableto vary the angular relation between it and the rotary shaft.

3. In a mechanical movement, a rotary shaft having a portion extendingat an angle to its axis of rotation, a sleeve or hearing member looselymounted on said angular portion, said sleeve or hearing member having atrunnion, and an oscillatory shaft having an angular relation to therotary shaft, said oscillatory shaft having a hub loosely mounted onsaid trunnion, a bearing for said oscillatory shaft, and means foradjusting said bearing to vary the angle between the oscillatory shaftand rotary shaft.

4. In a mechanical movement, a rotary driving shaft having a bearingportion standing at a fixed angle to its axis of rotation, an

oscillatory shaft adapted to turn about its longitudinal axis and havingan angular relation to the rotary shaft, and a swiveled connectionbetween said oscillatory shaft and the angular bearing portion of therotary shaft, and means to vary the character of the oscillatory motionof the oscillatory shaft without changing the rotary motion of therotary shaft.

5. In a mechanical movement, a rotary shaft'having a portion standing atan angle to its axis of rotation, a sleeve or bearing member looselymounted on said angular portion, said sleeve or hearing member having atrunnion, and an. oscillatory shaft having an angular relation to therotary shaft, said oscillatory shaft having a hub loosely mouifted onsaid trunnion, and being adjustable to var the angular relation betweenits axis an that of the rotary shaft.

6. In a mechanical movement, a rotary shaft, an oscillatory shaft, meansconnecting said shafts adapted to transform the rotary motion of therotary shaft into oscillatory motion of the oscillatory shaft, andadjusting means for varying the relative time of oscillation of theoscillatory shaft in different directions.

7 In a mechanical movement, a rotary shaft, an oscillatory shaft, meansconnecting said shafts adapted to transform the rotary motion of therotary shaft into oscillatory motion of the oscillatory shaft, andadjusting means for varying the relative time of oscillation of theoscillatory shaft in different directions without affecting the rotarymovement of the rotating shaft.

8. In a mechanical movement, a rotary shaft, an oscillatory shaftadapted to oscil" late on its lon itudinal axis, means connecting saidsha ts constructed and arranged to transform the rotary motion of therotary shaft into oscillatory motion of the oscillatory shaft and meansfor permitting the direction of the longitudinal axis of saidoscillatory shaft to be changed and for maintaining said shaft inchanged position.

9. In a mechanical movement, a rotary shaft having a portion standing atan angle to its axis of rotation, an oscillatory shaft adapted to rotateabout its longitudinal axis and having an inclined angular relation tothe rotary shaft, and a swivel connection between said oscillatoryshaftand the angular portion of the rotary shaft, whereby the relativetimes of the oscillations of the oscillatory shaft in differentdirections are different.

10. In a'mechanical movement, a rotary shaft having a portion standingat an angle to its axis of rotation, a sleeve or hearing member looselymounted upon the angular portion of the shaft, an oscillatory shaftpivotally connected to said sleeve or bearlng, the axis of theoscillatory shaft intersecting the axis of the rotary shaft and bein atan inclination thereto, whereby the re ative times of the oscillationsof the 0scillatory shaft in different directions are different.
